The ST-LINK-v2 , STLINK-V2/ISOL and ST-LINK-v3 are an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families.
The single wire interface module (SWIM for STM8) and JTAG or Serial (SWD) (for STM32, for programming the STM32 is suggested to use STLINK-UTILITY) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.

In addition to provide the same functionalities as the ST-LINK/V2, the ST-LINK/V2-ISOL features digital isolation between the PC and the target application board. It also withstands voltages of up to 1000 Vrms.

STM8 applications use the USB full-speed interface to communicate with the ST Visual Develop (STVD) or ST Visual Program (STVP) software.

STM32 applications use the USB full-speed interface to communicate with Atollic®, IAR™, Keil®, AC6 or TASKING integrated development environments.

STLINK-UTILITY software is here

stlink-utility

 

The complete SW kit for use the ST-LINK is formed of this parts:

  • STSW-LINK004ST-LINK UTILITY, for programming STM32 products (very easy to use)
  • STM32Cube Programmer – evolution of the ST-LINK UTILITY software for programming STM32 products
  • STSW-LINK007 – ST-LINK, ST-LINK/V2, ST-LINK/V2-1 firmware upgrade
  • STSW-LINK008 – ST ST-LINK/V2-1 USB driver on Windows Vista, 7 and 8 (old version)
  • STSW-LINK009 – ST-LINK, ST-LINK/V2, ST-LINK/V2-1 USB driver signed for Windows 7, Windows 8, Windows 10
  • ST-LINK-SERVER – The ST-LINK server is an application to share the debug interface of a single ST-LINK board among several host applications, typically a debugging tool and a monitoring tool. Of course, two debugging tools cannot simultaneously control the same target, but both may have access to it, if appropriate connection settings are chosen.

ATTENTION:
If you use ST-LINK UTILITY with the STM32 DISCOVERY or NUCLEO remember to select SWD protocol, see below.
